Islam Times - After nearly a full-term in office, US President Barack Obama's eligibility for presidency is being challenged as an Atlanta court has summoned him.

A Georgia judge has ordered President Obama to appear in court on Thursday for a hearing on a complaint that says Obama cannot be president as he is not a natural-born US citizen. It is, however, unclear whether a court could force a sitting president to appear in court.

California attorney Orly Taitz has filed the lawsuit which is challenging the presence of Obama's name on the March presidential primary ballot.

Taitz says she has been working on the case over the last three years.

“This will be 100 times bigger than Watergate,” she said referring to the 1970s political scandal that brought down former US President Richard Nixon adding, “There are high ranking judges and federal officials who are involved in this cover up. The ramifications of this trial will be enormous.”

Although Taitz said that she knew the president's legal team would fight his appearance in the Georgia court, she went on to say that, “If he [Obama] is appealing this decision, then he looks guilty. The whole nation understands this man is a fraud.”

Taitz's lawsuit is one of many such lawsuits filed nationwide against the president. Yet Obama campaign officials say such claims have no merit.

The Georgia judge has denied a motion by Obama's lawyer to nullify a subpoena that requires Obama to show up.

The allegations against Obama come as primaries and caucuses are scheduled to be held over the next few months in every US state to vote on the Republican Party competitors before a final nominee is elected at the party convention in August to challenge President Obama in the 2012 elections.
